OMG!! My fiance proposed! i said yes of course!?

he proposed to me with a diamond ring that I found out is $750! We have been together since high school, he moved away for a few years and came back in August, just for me! This is becoming a reality! High School Sweetharts to Bride and Groom to be! The date is set for December 1st. can someone please knock me into getting ready? Do anyone of you know a good bridal shop online? my fiance told me that to not put a spending limit. he wants me to have whatever i want. i don't want to spend that much money though. He works as a PT, so he gets a good paycheck... i don;t care how much money he has though, i love him! as of now i am living with him in his house his parents made for him. 2 storie 4 baths 3 bedrooms 2 master bedrooms 1 extra large living area 1kitchen 2 offices 1 library and 2 pantry areas and a basement. Oh his dad is a neorosurgeon and his mom's parents are rich. This house was his college graduation gift to him. He is 25. oh.. i am so sorry i am rambling, i am so excited
